Madonna to Cross Picket Line?

Fans attending Madonna's concert in Los Angeles this weekend will have more than traffic jams and ticket scalpers to worry about -- they'll also have to contend with hundreds of union picketers.

Organizers of the stage employees union have been stirring up interest in a Madonna picket since the star had a dress rehearsal at the Forum on Monday. The International Alliance of Theatrical Stage Employees has been locked out of the Forum since April 11 following a salary dispute with the stadium's owners. Jim Wright, a business rep for the union, says several hundred people are expected to rally at the concert on Sunday, and will urge concertgoers not to buy concessions or souvenirs at the Forum.

Wright said the union tried to convince the star to move her show to another venue, with no luck.

Calls to Madonna's reps were not immediately returned.
